5 Claims.

erence to the accompanying drawing forming a part of the specication and in which- Fig. 1 is a perspective view of an evaporator embodying the invention and shown in condition of use;

Fig. 2, an enlarged vertical section through the upperportion of said evaporator;

Fig. 3, a section taken substantially on line 3'-3 of Fig. 2;

Fig. 4, a partial view illustrating a modified form of construction; and

Fig. 5, a section taken substantially on line 5-5 of Fig. 4.

The embodiment of the invention illustrated in Figs. 1, 2 and 3 comprises a cylindrical wick I0 which is doubled upon itself to form a loop II, the doubled end of said wick being secured to the body thereof by means of a binding I2. A ring I3 is attached at the top of the loop II to facilitate adjustment of said wick. The wick thus provided is of a size and shape adapted to be ar-A ranged in a container, such as a bottle I4, having a mouth I5, through which said loop II is adapted and arranged to protrude 'as indicated.

As shown, the Wick I is of a diameter somewhat greater than one-half the diameter of the mouth I5 so that when said wick is doubled upon itself so as to form the loop I3, the width of said loop in one dimension being somewhat greater than the corresponding width of the mouth vI 5; whereby said wick will be compressed by said mouth in its greater dimension and expanded laterally in its lesser dimension, but thereby leaving drainage spaces I6 at each side of said loop. By this arrangement the loop may be readily withdrawn from the bottle I4 to the various positions of adjustment and opened or expanded, as indicated, in Fig. 1 to increase its exposed surface to correspondingly increase the rate of evaporation.

When it is desired to discontinue the evapora.

tion, the loop Il is compressed and forced downwardly through the mouth of the bottle into the body thereof, any liquids squeezed from said wick during this process draining back into the bottle through the spaces I6. Then the ordinary screw cap may be applied to the bottle, thus preventing any further evaporation.

In the modiiication'illustrated inFigs. 4 and 5, a square wick I1 is illustrated of transverse dimensions somewhat greater than one-half of the diameter of the bottle mouth so that the total width of the loop I8 will be somewhat greater than the corresponding diameter of 'said mouth and whereby the same results are obtained as before, any liquid squeezed from the loop I8 in replacing it in the bottle I4, draining into said bottle through the spaces I9 at each side thereof.

While I have illustrated and described the preferred forms of construction for carrying the invention into eiect, these are capable of variation and modication without departing from the spirit of the invention. I therefore do not Wish to be limited to the precise details disclosed, but desire to avail myself of such variations and modifications as fall within the scope oi the appended claims.

I claim:

1. The combination withl a container having a mouth, of a wick therein arranged to protrude through said mouth, said wick being of a thickness in one dimension somewhat greater than the corresponding dimension of said mouth and of a width in its other dimension slightly less than the corresponding dimension of said mouth,

.thereby causing compression of said Wick by said mouth in one dimension and expansion thereof in itsr other dimension to hold said Wick securely in various positions of adjustment and provide spaces at its sides for drainage into said container of liquid squeezed from said wick.

2. The combination with a container having a mouth, of an evaporating wick therein bent upon itself to form a loop for protrusion through said mouth, said wick being of a thickness somewhat- 3. The combination specified in claim 2 in A which the loop is substantially one-half the length of the wick.

4. The combination specified in claim 2 in which said wick is cylindrical in form.

5. The combination specified in claim 2 in which said wick is rectangular in cross section.
